A man’s heart pumps about 5.5 quarts of
blood each minute. Six quarts equals 24
cups; one cup is the same amount as in
the milk carton that comes with the typical
school lunch.

Gather a large container, such as a stock pot or an
empty cooler. Also rinse out several empty milk cartons
from the cafeteria. Have students predict if the container
will hold six quarts of water; then test it by inviting
students to fill the cartons with water and pouring them
into the container. Have the class track how many
cartons have been poured in the container, stopping
when the total equals 24 or when the container is full.
Use the results to compare the amount the container will
hold to the amount of blood pumped by a man’s heart
each minute.
